Welcome aboard!
Yea, i had the same thing happen to me on a solar panel as well. I would get some input on the quality of the latest mounts from Tek2000 if you were thinking of buying from them. My problem wasn't the wind so much as the inability of the sub-quality mount to handle anything more then gentle winds.
Make sure you find a location that is suitable to give you the most east arc to west arc. If you don't have to worry about snow, as long as you keep the pole height above ground at 1/2 the diameter of your dish, you should be okay there. I have to deal with a LOT of snow, so i keep it at 2 feet higher then that. The shorter you keep the pole the better. I would also fill the pole with concrete so it flexes less. Also, drill a hold through the pole at the bottom to run a rod through it so it will go into the ground with the concrete.. This will prevent the poll from rotating, which would be disastrous for reception and moral.
If you have prevailing winds, that aren't in your way, then you can shield yourself from that. We mostly have winds from the North, so, thats why I'm sheltered behind the house. But, if we get East winds, boy does my dish feel it. That's where the strong mount and pole and keeping it low makes a difference.
I'm sure others will have input as well..
